Well - the cm:content property is not a mandatory property so you can actually have documents without any content. In that case the content stream properties of CMIS can be null. So that is not a bug in the way Alfresco presents the document.
The question is what potentially went wrong during the upload - there could be an issue there.

Quoting the <a href="http://docs.oasis-open.org/cmis/CMIS/v1.1/cs01/CMIS-v1.1-cs01.html">CMIS 1.1 specification</a> (2.1.4.3.3):

<cite>The repository MUST return this property with a non-empty value if the document has a content stream and the property ﬁlter does not exclude it. If the document has no content stream, the repository MUST return "not set".</cite>

Here even though the object has a content stream (see its cmis:contentStreamId) it returns a null cmis:contentStreamFileName value.

I didn't notice the content stream ID and mimetype being set. Then yes, it's both a bug and violation of spec.
